Driving Down The Highway

Why is it , when I'm driving down the highway, only children look out the window and wave?

I always wave back, it makes me feel good, and it adds to the kids fun. well why not? Traveling on the highway can be so boring, especially when you don't have another passenger. I always look to see who's around me anyway, people tend to think that they're invisible, and do some pretty bizarre things in their car, like grooming, picking their noses, and yes........ even oral sex.... I've heard stories from trucker friends about that. They see it all.

So when you see a kid waving at you on your travels, wave back. It'll make your day.
